The EXC-1553UNET/Px is an intelligent, single- or dual-channel, MIL-STD-1553 adapter. Its small size and ability to interface through USB or Ethernet interfaces make it a complete solution for developing, testing and performing system simulation of the MIL-STD-1553 bus, both in the lab and in the field.

The DAS-429UNET/RTx is an intelligent, multichannel ARINC 429 interface device. Its small size and ability to interface through USB or Ethernet interfaces make it a complete solution for developing, testing and performing system simulation of the ARINC 429 bus, both in the lab and in the field. In addition, this device provides 8 I/O Discrete signals and an IRIG B input.

The M4K825CAN is an intelligent multichannel ARINC 825 (CAN bus) interface module for the multiprotocol Excalibur 4000 family of carrier boards. The module supports up to ten ARINC-825 channels.


The EXC-ETHPCIe/2 board is an Ethernet test board and supports two channels. The board also contains room for two standard 4000 modules that can support multiple channels of other avionics communications protocols including MIL-STD-1553, ARINC-429, Serial, Discrete, ARINC-708 and CANbus.

2000PCI Express multi-protocol ARINC-429 / 575 & more!

This cost effective board supports up to 2 modules, each module represents an independent test and simulation device. Modules currently include ARINC-429, ARINC-708 / 453, Serial (RS-232 /422/485), Discrete and CAN bus.

Databus monitor and analyzer

is a cost-effective avionics monitoring and simulation application for MIL-STD-1553 & ARINC-429 that streamlines data acquisition, processing and translation into meaningful engineering units, raw data and graphical displays.

Fully Integrated

An advanced, ruggedized PC104 and PC104+ system in an enclosed, modular casing. The system is appropriate as a mission computer or for use in data acquisition and recording for any combination of ARINC-429, MIL-STD-1553, Serial, Discrete or similar types of communication.

You have a device that needs to be tested but you are not at the location.

What can you do?

Now Excalibur has the MACC allowing control of your 1553 device over a distance using Ethernet.

Protocol Converter

The MACC is a complete Miniature Airborne Communications Converter (data converter) designed to convert bi-directional messages. 
The MACC converts messages between the following protocols:

♦ MIL-STD-1553 A/B
♦ ARINC 429 (T or R)
♦ ARINC 419
♦ Serial (RS-232/422/485)
♦ Discrete I/O's 
♦ Ethernet

Mini Data Recorder

Excalibur’s MARC is a complete Miniature Airborne ReCording system designed to record messages of several communication protocols:


♦ MIL-STD-1553

♦ ARINC-429 

♦ Serial (RS-232/422/485)

♦ Discrete I/O's

Embedded Boards

ARINC-429 PMC up to 20 channels

ARINC-708/453 PMC up to 4 channels

MIL-STD-1553/1760 PMC up to 4 channels

MIL-STD-1553/1760 VME up to 16 channels

Multi protocol

The EXC-4000P104plus is a multiprotocol P104plus interface board for avionics test and simulation applications. Each board holds up to five independent modules. Ideal for embedded systems.

PC/104 Plus Power Supply

The EXC-PSM104P85 power supply is a high performance 85 Watt power supply designed for aerospace, military and high-end industrial applications.The EXC-PSM104P85 is ideal for embedded solutions and is specifically designed to comply with MIL-STD-461E, MIL-STD-704A & E and MIL-STD-1275B.

Multi-protocol PCI Express

The 4000 PCI Express carrier board was developed to meet the needs of avionic testers for multi-protocol integrated, digital bus testing using PCI Express.

AS5643 (FireWire) - IEEE 1394b

The EXC-1394PCIe card for the PCI Express bus is an intelligent test and simulation card for interfacing to an IEEE-1394 data bus (AS5643). It implements a 1394b PHY layer, operating at 100, 200, or 400 Mbps.

MIL-STD-1553 Couplers

Box Couplers are the key component in the fabrication of your bus architecture. Excalibur provides a full line of standard couplers listed in the catalog as well as custom couplers to your requirements. Excalibur's products are cost competitive, with delivery from stock.

MIL-STD-1553 Bus Switch

MIL-STD-1553 Bus Switches are devices that enable system architecture to be reconfigured. This reconfiguration is mostly accomplished in the test environment and includes but is not limited to simulation of missile firing and switching in or out a new section of bus interface.

MIL-STD-1553 Repeater

The ESI-1553RPT MIL-STD-1553 Repeater box was developed for customers who need to extend the existing length of their bus or provide the capability to utilize long stubs or to connect a number of devices to a single stub.

MIL-STD-1553 In-line Couplers

IN-LINE COUPLERS are predominately utilized in airborne applications but can also be used where space is limited such as testers and simulators. The products were designed to meet the environmental requirements imposed by the military, including the temperature range of -55°C to 125°C.

MIL-STD-1553 Accessories

Excalibur provides a variety of terminators that includes, 78 ohm, 3K ohm and others.
